Last night at the 13th annual Latin Grammy Awards — held at the Mandalay Bay Events Center in Las Vegas — celebrities hit the red carpet in plunging necklines, short hemlines and enough sequins to drown a Rockette. You may not know some of these names or faces, but you'll never forget some of these outfits.

Red was a very popular color last night. Singer Desiree Estrada rocked a beauty pageant gown and oversized accessories.

Also in red: Singer Paulina Aguirre, wrapped up like a present. Singer/actress Mayra Veronica showing off that hourglass figure. Not shy.

Love all the feathers and bracelets on fresh-faced singer Duina del Mar.

Rosy, floral, formal: Singer Cristina Eustace.

Gray, but not somber: Model Alejandra Espinoza.

Retro vibe, complete with gold platform shoes for recording artist Deborah de Corral — who looks kind of like a cross between Alexa Chung and Sofia Coppola. Figure-hugging lace on singer Marilyn Odessa.

Not-so-basic-black: That's an insanely low neckline on My Lifestyle Magazine President and CEO Elizabeth Ortiz. Singer Ninel Conde looks like she might not be able to breathe. I've got a crush on the befeathered frock television personality Lourdes Stephen is wearing, and the slick sequined pants and tunic on singer Ana Victoria are very chic and modern.

Now we're entering the metallics: Gold on actress Odalys Garcia — she is her own award statuette.

Gunmetal: TV personality Karen Sierra, whose dress is so long and so low that if she takes a step forward and her foot pulls on the hem, her breasts will pop out and be set free.

These three are quite nice! In sparkling silver is Venezuelan model Alexandra Olavarria. In gold with a blouson bodice is singer America Sierra. And that show-stopping tigress gown singer Beatriz Luengo is wearing on the right is fierce.
